IMPROVEMENT IN DOMINOs.

Specification forming part of Letters Patent No. 91,234, dated J unc 15,1869.

To all lwhom it may concern.-

Be it known that I, JOHN W. HYATT, Jr., of the city and county ofAlbany, State of New York, have invented a new and Improved Method ofManufacturing Dominos; and I do hereby declare that the following is afull and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I willproceed to describe it.

Figure l is a strip of wood of a thickness slightly in excess of theproposed width of the domino and of a width slightly in excess of theproposed length of the domino. Fig. 2 is a section sawed from the stripshown in Fig. 1, taking so much of the strip as will make a blockslightly thicker than the finished domino, with the grain of the woodrunning perpendicular to the face and back thereof. Fig. is the blockshown in Fig. 2 aft-er having been colored. Fig. 4 represents the blockafter having been pressed in a suitable die or mold, which confines theblock of wopd on its side grain firmly while it is being pressed on itsend grain into the required form, leaving the depressions A A and themargins B, crossbar C, and spots D in relief, ani forming the smallholes e. Fig. 5 represen s a metallic or other suitable plate, withholes punched therein corresponding to the number of spots in one-halfof a domino, and made in all respects to exactly lit the depression A,and having a small hole, e, for a pin corresponding in position to thesmall hole e, Fig. 4.. Fig. 6 is a perspective vie-w of the finisheddomino, consisting of the block, Fig. 4, with the plates, such as areshown in Fig. 5, placed therein, allowing the elevated spots D, Fig. 4,to enter the holes in the plates, leaving the whole face ofthe dominoperfectly smooth and even, excepting the center-pin F, which has a headgreater in diameter than the width ofthe crossbar, and serves to holdthe inner edges of both plates, as well as to form a pivot for thedomino. The opposite edges are held by the small p ins c'. Fig. 7 is asectional view of the iinished domino, showing the several parts,consistin g of the stamped wooden block Gr, plates H, pins c', andcenter-pin F.

The plates may be made of brass, German silver, or plated metal, or ofivory or any other fine material.

The pores of the wood are filled with linsecd-oil, shellac, or othersuitable material, to protect it from the wet and to enable it toreceive a polish.

The advantages of this invention are cheapness and rapidity ofconstruction, exact uniformity in size, and greatly-increased hardnessof the wood, so that the domino is not easily bruised, scratched, orotherwise marked. The plates also, being all punched by the same dieexactly to match with the cavities A A', are more reliably fitted thanin work depending mainly upon the skill and faithfulness of theoperative, and are not liable to come loose from the back.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, is-

A domino with the perforated plates H and the embossed wooden back G,constructed substantially as described.
